Observation of Λb0 → ψ(2S)pK− and Λb0→ J/ψ π+ π− pK- decays and a measurement of the Λb0 baryon mass
The decays Λb0→ ψ(2S)pK− and Λb0→ J/ψπ+π−pK−are observed in a data sample corresponding to an integrated luminosity of 3 fb^−1, collected in proton-proton collisions at 7 and 8 TeV centre-of-mass energies by the LHCb detector. The ψ(2S) mesons are reconstructed through the decay modes ψ(2S) → μ+μ−an...
